Description：
IOTA FHTV 3270 is a fluorosilicone silicone compound that is formed by thermal vulcanization after adding a vulcanizing agent (the vulcanizing agent is selected according to the process requirements).
Advantages:
easy to process
Good mechanical properties, high strength and resilience
Excellent oil resistance, solvent resistance and high and low temperature resistance, low dielectric loss of transformer oil

*The data in the table are typical product performance and do not serve as factory standards.
*Meeting heat resistance requirements requires the addition of heat-resistant additives
Processing suggestions:
It is recommended to use 0.6 to 1 part of bis-penta-sulfide curing agent (2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane).
Customers should determine the most appropriate vulcanization temperature and time based on product size and vulcanization method.
Application:
Can be used for molded products, injection molding and extruded tube forming products; has good mechanical properties
Product packaging: 20Kg per box
Storage period:
IOTA FHTV 3270 should be stored in the original unopened packaging below 40℃ for 12 months from the date of production.
